Dean Foods Company has begun development of an anaerobic
digester on the Big Sky Dairy farm near Gooding, Idaho. The anaerobic
digester will capture animal waste from the farm’s approximately 4,700
dairy cows, reducing both odors and emissions of methane gas into the
atmosphere. The resulting captured methane will then be used to generate
electricity. The project, which is expected to be operational by early
2009, will be owned and operated by a partnership between Dean Foods
and AgPower Partners, LLC which consists of an affiliate of Andgar Corporation,
an affiliate of GHD, Inc.and Cenergy USA, Inc.

The Big Sky Dairy digester project is expected to have
generation capacity of more than one megawatt per hour of renewable “green”
power, which will be sold into the local power grid and should provide
enough renewable energy annually to power approximately 650 homes. In
addition, the digester will produce a sanitary fiber by-product that
can be used as clean animal bedding or as organic soil enhancement.
